Classic béarnaise is one of those sauces that feels impossibly luxurious, and this fennel-forward version takes it somewhere even more interesting. The aromatic reduction — built from white grape juice, water, fresh tarragon stems, and finely chopped fennel — gives the finished sauce a subtle anise brightness that cuts right through the richness of the butter. Speaking of butter: that's the only fat here, full stop. No seed oils, no neutral cooking sprays, no hidden vegetable blends — just real unsalted butter whisked in piece by piece until the sauce is glossy, thick, and absolutely silky. For anyone avoiding industrially processed oils, that kind of ingredient clarity is genuinely hard to find in a restaurant-style sauce. The double-boiler method keeps the egg yolks from scrambling while building that signature velvety body, and pulling the sauce to 160°F means you're hitting the food-safety mark without sacrificing texture. Finish it with a handful of finely chopped fresh tarragon leaves and you've got something that belongs draped over a perfectly cooked steak, spooned onto roasted vegetables, or honestly eaten with a spoon straight from the bowl.

Ingredients

4 servings

For the reduction

3 tbsp white grape juice
3 tbsp water
1 tbsp fresh tarragon stems, roughly chopped
2 tbsp fennel bulb, finely chopped

For the sauce

3 pasteurized egg yolks
½ cup unsalted butter, cut into 1-tbsp pieces
¼ tsp salt
2 tbsp fresh tarragon leaves, finely chopped

Instructions

1
Combine the white grape juice, water, chopped tarragon stems, and fennel in a small saucepan over medium heat. Bring to a simmer and cook until the liquid reduces to about 2 tablespoons, 5–7 minutes. Pour through a fine-mesh strainer into a heatproof bowl, pressing the solids to extract all the liquid; discard the solids.
